The Improvement of Dental Air polishers

Dental air polishers are used routinely in general dental practice for plaque and stain removal and for every situation when enamel is cleaned, such as prior to bonding procedures.

A rubber cup and fluoridated prophy paste method has been used for plaque and stain removal. However, this technique has obvious limitations in areas of crowding, around orthodontic fixed appliance and of course, in areas of limited access such as under and around fixed multiple unit restorations.

Air polishing units typically generate a stream of pressurized air, carrying specially graded particles of a mild soluble abrasive, such as sodium bicarbonate. The abrasive is directed, in the presence of a stream of water, at a tooth surface to be cleaned. The mixture of water and powderladed stream occurs on the tooth surface and forms a “slurry” that is responsible for the cleaning action.

In most currently available units, the water stream emits through a separate nozzle that may be concentric to that of the powderladen air stream nozzle. The resulting buildup of crystalline anhydrous sodium bicarbonate deposits in the lumen of the air/powder nozzle results in clogging.

More recent technology produces a slurry by introducing the water stream into the powder-laden air stream, within the spray head at a critical moment, to produce a fully homogeneous stream that is emitted from a single nozzle. This stream technology configuration has not only been shown to prevent nozzle clogging by preventing the buildup of deposits, but also results in a much more efficient cleaning action because the slurry is formed prior to emission.

They have been considered to be the equipment of choice for the hygiene department, sometimes being combined with ultrasonic scaler. They offer a large powder chamber holding enough powder for multiple treatments, along with the convenience of a lightweight, fully autoclavable handpiece design. They are activated by a dedicated foot control that can select either a polishing or rinse mode and they require connections to water, air and electrical outlets.
